Brian L. Roberts, Chairman and Chief Executive Officer of Comcast Corporation, said,
The third quarter continues our momentum. Cables results show real strength in every part of the business, producing sustainable and profitable growth while we expand our product offerings, deliver more innovation and continue to
transform the customer experience.

NBCUniversals results highlight the strong performance of the Olympics and steady progress in
its businesses as we invest to build value. The London Olympics exceeded all our expectations and our entire company contributed to their success, proving how effective we can be when we bring together our unique assets and capabilities.

Earnings per Share (EPS) for the third quarter of 2012 was
$0.78, a 136.4% increase from the $0.33 reported in the third quarter of 2011. Excluding a $0.20 per share gain related to our share of SpectrumCos sale of wireless spectrum licenses and a $0.12 per share gain on the sale of
NBCUniversals interest in A&E Television Networks, EPS increased 39.4% to $0.46 in the third quarter of 2012 (see Table 4).

EPS for the nine months ended September 30, 2012 was $1.72, a 67.0% increase from the $1.03 reported in the prior year. Excluding
non-recurring gains on sales in 2012, and NBCUniversal transaction and related costs and other non-recurring items in the first nine months of 2011, EPS increased 27.3% (see Table 4).

Free Cash Flow (excluding any impact from the Economic Stimulus packages) for the third quarter of 2012 increased 8.8% to $1.5
billion compared to the third quarter of 2011, reflecting growth in consolidated operating cash flow, partially offset by higher taxes and capital expenditures. Free cash flow for the nine months ended September 30, 2012 increased 19.0% to $6.1
billion compared to $5.1 billion in 2011.

Pro
forma results are presented as if the NBCUniversal transaction, which closed on January 28, 2011, and the Universal Orlando transaction, which closed on July 1, 2011, were effective on January 1, 2010. These results are based on
historical results of operations, adjusted for the effects of acquisition accounting and eliminating the costs and expenses directly related to the transaction, and are not necessarily indicative of what the results would have been had Comcast
operated NBCUniversal and Universal Orlando since January 1, 2010 (see Table 5 for reconciliations of pro forma financial information).

Consolidated Revenue increased 15.4% in the third quarter of 2012 to $16.5 billion compared to
$14.3 billion in the third quarter of 2011. Excluding $1.2 billion of revenue generated by the 2012 London Olympics, consolidated revenue increased 7.1%. Consolidated Operating Cash Flow increased 9.5% to $5.0 billion compared to $4.6
billion in the third quarter of 2011. During the third quarter, the Olympics generated $120 million of operating cash flow which reflects the settlement of a $237 million unfavorable contract recorded in acquisition accounting in 2011. Excluding any
impact from the Olympics, consolidated operating cash flow increased 6.9% (see Table 6).

Revenue for Cable Communications increased 6.9% to $10.0 billion in the third quarter of 2012
compared to $9.3 billion in the third quarter of 2011, reflecting increases of 8.8% in High-Speed Internet, 33.6% in Business Services, 2.7% in Video and 23.5% in Advertising. Monthly average total revenue per Video customer increased 8.7% to
$150.73, reflecting a growing number of residential customers taking multiple products, rate adjustments and a higher contribution from Business Services.

Operating Cash Flow for Cable Communications increased 7.7% to $4.0 billion in the third quarter of 2012 compared to $3.7 billion in the third quarter of 2011, reflecting higher revenue, partially
offset by increases in video programming and higher sales and marketing expenses to support growth and enhance our competitive position in both residential and business services. This quarters operating cash flow margin was 40.1% compared to
39.8% in the third quarter of 2011.

Capital Expenditures for Cable Communications increased $110 million or 8.8% to $1.4
billion in the third quarter of 2012 compared to the third quarter of 2011, primarily reflecting continuing investments in network infrastructure, the expansion of business services and other new product roll-outs. Cable capital expenditures
represented 13.7% of Cable revenue in the third quarter of 2012 compared to 13.4% in last years third quarter.

For the nine
months ended September 30, 2012, Cable capital expenditures increased $56 million or 1.6% to $3.5 billion, representing 12.0% of Cable revenue compared to 12.6% in 2011.

Combined Video, High-Speed Internet and Voice Customers increased by 294,000 in the third quarter of 2012, a 28.1% increase compared to third quarter 2011 net additions. As of September 30, 2012,

Pro forma NBCUniversal results are presented
as if the NBCUniversal transaction, which closed on January 28, 2011, and the Universal Orlando transaction, which closed on July 1, 2011, were effective on January 1, 2010.

Revenue for NBCUniversal increased 31.2% to $6.8 billion in the third quarter of 2012 compared to $5.2 billion in the third quarter
of 2011, primarily driven by 2012 London Olympics revenue of $1.2 billion in the Broadcast Television segment. Excluding the Olympics, NBCUniversal revenue increased 8.3%. Operating Cash Flow increased 19.9% to $1.1 billion compared to
$951 million in the third quarter of 2011 and included $120 million of operating cash flow generated by the Olympics. Excluding the Olympics, operating cash flow increased 7.3% (see Table 6).

For the nine months ended September 30, 2012, NBCUniversal revenue increased 15.7% to $17.8 billion. Excluding $259 million of revenue related
to the Super Bowl in the first quarter and the impact of the Olympics in the third quarter of 2012, revenue increased 6.3%. Operating cash flow increased 8.0% to $2.9 billion compared to the first nine months of 2011. Excluding the Olympics,

Cable Networks

For the third quarter of 2012, revenue from the Cable Networks segment increased 3.2% to $2.2 billion compared to $2.1 billion in the third quarter of 2011, reflecting a 5.7% increase in distribution revenue and
flat advertising revenue. Operating cash flow increased 7.6% to $809 million compared to $751 million in the third quarter of 2011, primarily reflecting higher revenue, and flat programming and marketing costs due to timing.

For the nine months ended September 30, 2012, revenue from the Cable Networks segment increased 4.2% to $6.6 billion compared to $6.3 billion
in 2011. Operating cash flow decreased 0.5% to $2.4 billion compared to the first nine months of 2011.

Broadcast Television

For the third quarter of 2012, revenue from the Broadcast Television segment increased 83.8% to $2.8 billion compared to $1.5 billion in the third
quarter of 2011 and included $1.2 billion of revenue generated by the 2012 London Olympics. Excluding the Olympics, revenue increased 5.2%. Operating cash flow was $88 million, which included $120 million of operating cash flow generated by the
Olympics, compared to a loss of $7 million in the third quarter of 2011. Excluding the Olympics, operating cash flow declined by $25 million reflecting higher programming costs related to an early start of our fall TV season and news coverage of the
Presidential election (see Table 6).

For the nine months ended September 30, 2012, revenue from the Broadcast Television segment
increased 35.3% to $6.2 billion compared to $4.6 billion in 2011. Excluding the Super Bowl in the first quarter and the Olympics in the third quarter of 2012, revenue increased 3.6%. Operating cash flow increased 35.2% to $274 million compared to
$203 million in the first nine months of 2011. Excluding the Olympics, operating cash flow declined by $49 million to $154 million compared to the first nine months of 2011 (see Table 6).

Filmed Entertainment

For the third quarter of 2012, revenue from the Filmed Entertainment
segment increased 23.6% to $1.4 billion compared to $1.1 billion in the third quarter of 2011, driven by higher theatrical revenue from the strong box office performance of Ted and The Bourne Legacy. Operating cash flow increased 31.1%
to $72 million compared to $54 million in the third quarter of 2011, reflecting higher theatrical revenue, partially offset by an increase in the amortization of film costs.

For the nine months ended September 30, 2012, revenue from the Filmed Entertainment segment increased 13.6% to $3.8 billion compared to $3.3 billion in 2011. Operating cash flow was a loss of $5 million
compared to a loss of $65 million in the first nine months of 2011.

Theme Parks

Theme Parks results are presented as if the Universal Orlando transaction, which closed on July 1, 2011, was effective on January 1, 2010.
As a result, Theme Parks segment revenue and operating cash flow includes the results of Universal Orlando, Universal Hollywood and international licensing fees.

For the third quarter of 2012, revenue from the Theme Parks segment increased 5.8% to $614 million compared to $580 million in the third quarter of 2011, driven by solid performance at the Orlando and Hollywood
parks. Third quarter operating cash flow increased 11.2% to $316 million compared to $285 million in the same period last year.

For the
nine months ended September 30, 2012, revenue from the Theme Parks segment increased 4.9% to $1.6 billion compared to $1.5 billion in 2011. Operating cash flow increased 10.0% to $708 million compared to $644 million in the first nine months of
2011.

Headquarters, Other and Eliminations

For the nine
months ended September 30, 2012, NBCUniversal Headquarters, Other and Eliminations operating cash flow loss was $444 million compared to a loss of $479 million in 2011 which includes non-recurring transaction-related costs that totaled $112
million.

5

corporate operations, Comcast-Spectacor and eliminations between Comcasts businesses. For the quarter ended September 30, 2012, Corporate, Other and Eliminations revenue was ($254) million compared to ($192) million in 2011. The operating
cash flow loss was $130 million compared to a loss of $91 million in the third quarter of 2011 reflecting an increase in eliminations associated with the 2012 London Olympics.

For the nine months ended September 30, 2012, Corporate and Other pro forma revenue and eliminations were ($637) million compared to ($523) million in 2011. The pro forma operating cash flow loss was $289
million compared to a loss of $256 million in the first nine months of 2011.

Notes:

1

We define Operating Cash Flow as operating income (loss) before depreciation and amortization, excluding impairment charges related to fixed and intangible
assets and gains or losses on the sale of assets, if any.

2

Earnings per share amounts are presented on a diluted basis.

3

We define Free Cash Flow as Net Cash Provided by Operating Activities (as stated in our Consolidated Statement of Cash Flows) reduced by capital expenditures,
cash paid for intangible assets and cash distributions to noncontrolling interests; and adjusted for any payments and receipts related to certain nonoperating items, net of estimated tax benefits. We do not present Free Cash Flow on a pro forma
basis.

All percentages are calculated on whole numbers. Differences may exist due to rounding.
